Thread: Two or three axis DRO
25/02/2021 20:38:49

I bought the 3-axis DRO for mine, anticipating that I would fit a Z at some time.

The quill is a short throw device and if you ever move the head in the middle of a set-up you have lost the accuracy, especially if you are an amateur who does not own fag papers.

I see that they can also do rotary encoders, so I may be able to get my turntable fixed up on the DRO. That would be a project and a half.

smiley great progress.

I would recess the top of the firebox. Is there boiler under it at that point?

Thread: WM16B measurement needed
20/02/2021 23:22:49

That looks the business. smiley

Yo Clay - welcome to the 16B club

There are a few errors in the Warco website,

I found one of them the hard way - the chip tray dimensions are the wrong way round, you need 520mm depth to fully support the tray, 500 is fine, mine is even less and the base of the machine is fully supported.

The distance of the Z-axis wheel to the wall is OK, I will be putting some slippy plastic on the rough wall nevertheless.

The machine is not as high as the maximum height listed, so I didn't have to move my lights.

My brain is failing - please use the link under my name to see the pictures. Other wise here is my thread:

Thread: Advice on benchtop milling machine

Small X/Y tables for very light use are available on ebay for very little money. They might do what you want.

Horses for courses always works, if you have the space and cash its bound to be OK.

Thread: High Temperature Air Source Heat Pumps for Domestic Heating
19/02/2021 23:02:53

News - we worked out that wood smoke was irritating our Covid-scarred lungs, so we are heating everything with oil-filled heaters on max-price electricity. The house smells better but I dare not look at the meter. blush

Thread: WM18 - Broken it again :(
19/02/2021 22:57:57

Good thread.

It seems that sanity has occured.

Anything that lets heat out will be a great help, a big fan like that should be fine cooling so small a box, its designed to get 600W out of a big empty box of sensitive electronics after all.

Thread: What Did You Do Today 2021
19/02/2021 22:24:45

I finally got out into the workshop!

I have been poorly recently and also focused on stuff in the house. I was made more determined by the stress of having both my mother and wife being of concern.

My mum is almost 80 and appears to have caught Covid during a hospital visit for chemotherapy, during which she also had an adverse reaction to the treatment that needed emergency treatment. You couldn't write it.

An afternoon of carpentry, has done me the world of good. I am building a fume cupboard, that will allow me to paint, weld, solder and steam when the weather is poor. Now the frame is up it looks about the right size. Lord knows where the sashes are coming from. The fan is sorted, not a proper EX-rated one but it should be OK if I keep the solvents to a minimum. Filters are easy - kitchen hood carbon filters are great.

A bit more tomorrow and I will be able to fit the vice I have been renovating and maybe even take the surface plate from out of under the sideboard and out into the workshop. The big bonus will be stocking up the drawers with all the tools from the house that I can never find when I want them.

Thread: Warco WM 18 vs GH 18 for CNC conversion
16/02/2021 21:32:17

I didn't know home-build CNC was such a big thing, looking at these links its huge!

16/02/2021 19:08:03

I am sure the WM 18B is the same as the PM-30V, My WM16B came with a PM-25 users manual. The only real difference is the interlocked cover over the top, which I like as its quick to open and close.

Good choice. It's a beast in the flesh, I saw one at Warco's showroom last summer.

Chunky yet already belt drive. smiley

Thread: CNC Lathe Scratch Build
15/02/2021 22:19:34

cool Super cool - and great progress. Well done.

Thread: Plans for updating the archaic forum?
15/02/2021 21:56:21

smiley Another vote for " beware what you asked for".

I am an enthusiastic member of The Unofficial Mamod and Other Steam Forum, it used to be huge, then the host organisation decided to change and the owner (a volunteer not a company) decided to take the opportunity to modernise and migrate to another host.

Result - huge number of threads where lost during the migration, promises (and contracts) broken. A large number of members dropped out, some because they didn't like the cosmetics, other offended that their careful work had been deleted, some to avoid the bitterness.

Fortunately the community has some robust individuals and has survived and regained some strength but the migration was at great cost, especially the cost of the huge loss of information.

This <CTRL>+<right click> is wonderful. party

Thread: Doncaster Show.
15/02/2021 21:20:34

May would be very optimistic.

Thread: 1/20th Scale Traction Engine
12/02/2021 20:17:55

Always a good idea to check the proportions...and generally admire. angel

Thread: Pennsylvania A3 Switcher
10/02/2021 20:29:51

Great progress!

How does the switcher compare with other 3.5" "starter" engines?

It looks capable, and I want a 0-4-0 for reasons of flexibility.

Thread: Workshop/Garage Insulation/Space Heating
10/02/2021 20:08:49

smiley I turned the thermostat on the little oil-filled rad down, it was too hot at 17C, and probably too expensive too. I am glad the insulation is so good, it was worth it.

Thread: crane uprate - where would you add some metal ?
09/02/2021 21:22:24

smiley Another qualified engineer voting for "don't do it".

My main argument is stability, there will be a little bit of safety factor on a static lift, and its probably been tested moving on a nice level and smooth floor, but cause it to twist or tilt and all bets are off, all the forces get very large and that safety margin disappears.

Quite frankly its barely fit for purpose as-is, I suggest you enjoy its economy.

Thread: Cosworth V8 1:12 scale
07/02/2021 18:14:19

cool well done, too fiddly for me!

Thread: Class 22 Diesel (next project)
07/02/2021 14:15:10

I have got to admit that lead makes good ballast.

I have used plenty of it myself. smiley
